Over the past few weeks I've given my friend Rich a hand a couple of times using his Turbo Saw Mill to produce useful timber from some wood he's coppiced. Here's a timelapse of us using the swing-arm circular saw, driven by a chainsaw engine, to produce batons from a sweet chestnut log:

And here's a video demonstrating the slabbing attachment, which is basically a big chainsaw with a 5' bar and a system to suspend it from the mill beam:

Having seen someone make a wooden bench using only a chainsaw and a sledgehammer, with no nails or screw, I thought I'd have a go, but making a table for use at the camp in the woods rather than a bench. As it was my first attempt I decided to use an old piece of sweet chestnut I'd had sitting around for a few years.

First I raised it up off the ground:
Then used the chainsaw to rip it down the middle, cross-cutting when I had a long enough section:

Then I put the two pieces side by side on some bearers. I flipped one of them round though, so that the combined width of the two of them is about the same all the way along.

To get them to fit together nicely, I then used the chainsaw to rip along the gap between them, then push them together. Having repeated this a few times I got a nice fit:

The next step was to make a 'dovetail joint'. I made two cuts with the chainsaw like this:

Then used a bore (or plunge) cut, followed by a bit more fiddling around with the saw to get it looking like this. You can see I've also used the saw to roughly shape a wedge of wood to go into the gap as well:

Having inserted the wedge into the gap, I then used the chainsaw to carefully rip along both sides of the wedge, taking care to take wood off the wedge rather than the table top logs.

Having repeated that several times, the wedge now fitted nicely:

After using the sledgehammer bang it securely into place, I then used the chainsaw to trim off surplus wood, so it looked like this:

Then did it all over again at the other end:

For the legs, I used the chainsaw to rip another log in half, and made four pieces like this:

Then I used a bore cut with the chainsaw to make holes in the table top, trimmed the tops of the legs, and hammered them through the holes:

Here it is with four legs in place:

Of course, when I turned it over it was far from level!

But a bit of trimming on the ends of the legs got that sorted:

The final step was then to use the saw to cut off the bits of leg poking through the top, and tidy up any rough spots:
